Following his defeat at Cloud City and Darth Vader's stunning revelation, Luke makes his recovery in the care of Leia and the Rebellion's finest medics. His new artificial hand is a sobering reminder of the power of the Dark Side, and his near brush with death. Resolving to complete his training in the face of these challenges, the young Jedi returns to Dagobah to seek answers from his old master Yoda, but arrives in time to find the ancient Jedi nearing the end of his long life. With his master's passing, Luke becomes the last of the Jedi... but a new hope is kindled when Luke learns of his twin sister, Leia, and the promise they both hold for the return of the Jedi.

Upon Luke's return, the Rebellion launches its final, desperate attack on the Empire, a perilous strike against the new Death Star. Luke and his friends form a covert strike team to disarm the Empire's crucial defenses on the forest moon of Endor. Luke feels the powerful presence of his father, Darth Vader, but rather than sewing doubt and fear, the Sith Lord's proximity only strengthens the young Jedi's determination to confront him one more time. Staking everything on his belief in the innate goodness that must reside somewhere within the Dark Lord, Luke leaves his friends and seeks out Darth Vader, giving himself up to the Empire as a prisoner.

Confronting his father, Luke appeals to the man Vader used to be, the courageous Jedi Knight, Anakin Skywalker, but it is only when he makes the ultimate sacrifice, refusing to fight Vader in the full knowledge that this will mean his own death, that Luke's appeal reaches the Dark Lord's heart. Turning on his Emperor, Vader saves Luke and destroys the Sith in one action, thereby fulfilling his destiny and securing the future of the Jedi. But it is Luke's resolute belief in Vader and his commitment to the Jedi ideals that have truly saved the galaxy and the soul of Anakin Skywalker.
